Abstract:
In 1962 the Institute of Horticultural Engineering at Hannover tested the irrigation distribution of a great number of nozzles of different makes under variable circumstances.
The obtained measuring dates were so numerous, that for the working out of these dates a computer was used.
At first it was the intention to work out a program with which the average value, the leakage and the aberration coefficient for each radius separately are to calculate, and also the average value over all distances till 75% of the total range.
Moreover this program contains a paragraph for the calculation of a special figure, which can be
